Application filed earn a,

To all whom it may concern:

Be it known that I. NOEL LANeToN CLARKE, a subject of the King of Great Britain and a resident of the city of Toronto, in the count of York, in the Province of Ontario, anada, have invented certain new and useful Improvements in Lubricant Disfication.

My invention relates to improvements in lubricant dispensers and the object of the invention is to devise a dispenser that will be rapid in action in order that the lubricant cups on the vehiclecan be filled in the minimum space of time.

A further object is to devise means for introducing air into the container of the dis-' penser which when the control valve is opened forces the lubricant from the container.

A still further object is to devise means whereby a predetermined quantity of lubricant can be withdrawn from the container and injected into the lubricant cup at one operation of the dispenser actuating means, and another object is to devise means whereby separate actuating means are supplied connected to a single lubricant container in order that the lubricant may be dispensed at different points.

My invention consists of a lubricant dispenser constructed and an-anged all as hereinafter more particularly describedand illustrated in the accompanying drawing in which:

Fig. 1 represents a vertical section through a lubricantcontainer showing my device applied thereto. j

ig. 2 is an enlarged vertical section of the means for forcing the lubricant from the container into the lubricant cups to be filled.

Fig. 3 is a cross sectional view through the line 3-3 Figure 2.

Fig. 4 is a vertical section through the air inlet valve on the top of the container illustrated in Figure 1, and

Fig. 5 is a diagrammatic view of the container showing a plurality of injectors connected thereto.

Like characters of reference indicate corresponding parts in the different views.

1 is the lubricant container provided with the filling cap 2 in the top thereof which also is provided with the orifice 3'into which is inserted the injector casing 4:, preferably of which the following is the speci 1%2. Serial Flo. 543,535.

sage-way 8 with a vertically disposed pas-- sage-way 9 offset from the centre of the casing and connected at its upper end to the flexible tube 10 which is fitted with a bayo- 6 net socket 11 on its free end adapted to extend over the nipple 12 of the lubricant cup 13. p

14 is a plunger reciprocable in the bore 7, said bore being provided at its upper end with a stufing box 15 through which the plun er extends.

h upper end of the plunger is connected by means of the link 16 to one end of the operating lever 17 which is fulcrumed on a bracket 18 secured to the top of the container.

19 is an inverted U-shaped stop secured to the top of the container 1 and straddling the lever 17 in order to limit its upward movement. 4

20 is an air inlet valve for the container adapted to extend through the'top thereof and to be connected to the ordinary air-service line in order to pump air into thecontainer. It is to be understood that the air valve can be of any suitable construction as for example the form. illustrated in Fig-' ure 4.

21, is a pipe connected at itsupper end to the bottom of the injector casing 4 and communicating with the vertical orifice 5, said we 21 plugged at its lower end and provid with the holes 23 in the wall thereof immediately above such plugged lower end. The pipe 21 extends down into the vicinity of the bottom of the container and is ada ted to receive the lubricant.

e operation of the device is as follows:

Air is pumped from the air-line into the container 1 through the valve 20 until there is suflicient pressure in the same, the plunger 1% being in its lowermost position wherein the exposed end of the horizontal passa e 6 communicating with the bore 7 is close by .such plunger. The socket 11 on the tube 10 is now connected to the nipple of the lubri cant cup and by pressing down on the free end of the lever 17 the plunger 14 is raised until it is in the position illustrated in Figure 1 wherein the exposed end of the passage 6 is opened. The tube 21, passage-way 5 and horizontal passage-way 6 have previously been filled with the lubricant and when the plunger is raised as above described,- the lubricant is forced down the bore 7, through the communicating passageway 8, up'through the passage-way 9 into the flexible tube 10 and thence into the lubricant cup.

It is obvious that if the plunger 14 is depressed again, immediately it reaches the upper end 0 its stroke and assuming that all the pipes and passages are filled with the lubricant, a fixed quantity of lubricant, corresponding with the volume of the bore will be forced out of the free end of the tube 10 into the lubricant cup. Then this is done it will be apparent that considerable pressure will be exerted in forcing the lubricant out of the free end of the tube 10 by the depression of the plunger 14 to the lower limit of its stroke and the faster the plunger is operated in a downward direction, the greater will be the speed of the lubricant ejected from the free end of the tube. Consequently it will be seen that a predetermined quantity of lubricant can be ejected from the tube if desired under considerable pressure, and this is of advantage in injecting the lubricant into lubricant cups that have become filled with dirt or gummed up.

It is apparent that as the plunger is depressed below the exposed end of the passage-way 6 the flow of grease from the container will be cut ofi, and thus only the amount in the bore will be ejected. 0n the other hand should it be desired to fill a large container or other lubricant receiving vesnaseaee sel with the-lubricant, it is only necessary to raise the plunger 14 as illustrated in Figure 1 by depressing the free end of the lever 17 and holding it in this position wherein the air pressure will force the lubricant from the passage-ways 5 and 6, through the bore 7, passage-ways 8 and 9 into the tube 10, expelling it from the free end thereof in a continuous flow.

In the diagrammatic view illustrated in Figure 5 a plurality of injectors are used connected to a single container and this multiple construction is of particular advantage where it isdesired to use a central lubricant tank in a garage or other building and provide injectors to facilitate lubricating cars at diffeient points.

From the above description it will be seen that I have devised a simple and effective lubricant dispenser which can be readily installed at a low cost and which will provide means for lubricating cars with great facility, thus eiiecting a considerable saving of time.

What I claim as my invention is:

In a lubricant dispenser, the combination with the closed lubricant container, of means for admitting air under pressure thereinto, an injector casing inserted into the container, said casing having a vertical lubricant inlet passage extending upwardly from its lower end and communicating with an intermediately disposed cross passage communicating with a vertical plunger receiving bore, and a vertical lubricant discharge passage extending upwardly to the top of the injector casing, said discharge passage communicating with the plunger receiving bore at its lower end, a reciprocable plunger in said bore, a delivery pipe connected to the upper end of the discharge passage and means for reciprocating the plunger,
